That satisfies only half of the problem. The slope of e^x and the area under the curve of e^x are equal, but the arc length of e^x is different.

Wow, just finally finished eh? Well I do think I'm back temporarily, I leave to our states capitol Olimpia, Washington on March 2nd for a week as a page.

Well, no problem with this till now for sure but imagine that he eytracts all of them and shares somewhere...

Thank you , that makes things very straightforward and easy.

Crazy, I'm surprised also. Thanks!

I'll give it a go, thanks!

Yeehaaa here's a dummy way with a tetrahedron fudge your model with a face on x,y plane and one edge on the x axis - you hope. this face must be filled draw a flat rectangle joining this edge at both end and extend along the flat plane y. It should fill by itself. the line in between can be removed and it should all fill - if not you screwed up placing your model I think this is fundamental to any modelling (would you start a 2d drg without an origin, scale and xy directions [image: iKQz_coplanarity.jpg]

Men... this is completely awesome!!! ver 2.2 works perfect... but in a non developer language, what will clean do? again, THANK U VERY MUCH!

Yes, you can safely remove skin.rb. It was a nice plugin at its time but now Curviloft (and also other plugins) can do more and nicer.

Everybody in the UK has heard of this place in Wales, but others might find this interesting.When I was about 10yrs old I tried to remember and learn how to say this place name, then I got interested in girls and tried to be less of a nerd. http://www.llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.com/ Also I found this site about long words. I am actually still a nerd. http://www.everything2.com/index.pl?node_id=1534419

you have any idea how to export the animation into a video, we would like to export the animation we did in skethup physics in to an video as then it would be easy for the presentation....

I just have to show this one, done in Kerkythea. [image: PT1Z_upin.jpg] [image: 4GqO_upin1.jpg]
